SPECIFICATION forming part of Letters Patent No. 354,053, dated December7, 1886.

Application filed February 23, 1886. Serial No. 192,942.

To all whom it may concern.-

Be it known that I, WILLIAM FRANKLIN, of Corry, in the county of Erieand State of Pennsylvania, have invented a new and useful Improvement inPinch-Bars, of which the fol lowing is a specification, reference beinghad to the annexed drawings, forming a part thereof, in which Figure lis a side elevation of my improved pinch-bar. Fig. 2 is an endelevation. Fig. 3 is a longitudinal section of the base of thepinch-bar.

Similar letters of reference indicate corre sponding parts in thedifferent figures of the drawings.

The object of my invention is to provide a pinch-bar operated bycompound levers.

The invention consists of the combination of parts, including theirconstruction, substantially as hereinafter fully set forth, and pointedout in the claim.

The base A of my improved pinch bar is provided on opposite sides withcars a, which project downward a short distance over the head of therail to which the pinch-bar is applied and hold the base in position foruse. In the upper side of the pinch-bar is formed a longitudinal slot,1), in which is pivoted the pinch-bar lever B on the pin 0. The shorterarm, (I, of the pinclrbar lever is tapered and turned upward, and thelonger arm, 6, of the pinch-bar lever is connected by links fwith thehand-lever O, which is also pivoted in the slot b, at the opposite endof the base A.

The end of the base A, in which the pinchbar lever B is pivoted, iswider and stronger than the opposite end, and is rounded to permit it topass partly under the car-wheel to which the pinch-bar is applied. Themanner (No model.)

of applying and using my improved pinchbar is shown in Fig. 1, theshorter arm being inserted between the wheel and the track, as near thepoint of contact of the wheel with the track as possible, when thehand-lever O is pushed over away from the car-wheel and toward thetrack, raising the shorter arm of the pinch-bar lever B, thus pushingthe carwheel forward. The extremity of the shorter arm of the pinch-barlever is rounded to form a suitable bearing-surface.

After depressing the hand lever 0 once, thus starting the car wheel, thehand lever is quickly raised and the base A is pushed forward to bringthe pinch-bar leveragain into engagement with the car-wheel. In thismanner the motion of the car may be rapidly accelerated. 7

By employing a system of compound levers in my improved pinch-barheavier loads can be moved forward with less exertion than is requiredwith a pinchbar ofthe ordinary form.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

As an improved article of manufacture, a pinch-bar formed of alongitudinally-slotted base, A, provided with cars a, the pinch-barlever B, pivoted in the base and provided with a tapered and roundedend, the hand-lever O, pivoted in the slot of the base-piece, and linksf, connecting the pinch -bau lever with the hand-lever, substantially asherein shown and described.
